For its second season, Betty White's Off Their Rockers will be pairing the 90-year-old funny lady with celebrity guest stars. White's old Mary Tyler Moore Show co-star Ed Asner will be among the famous faces appearing in comedy bits that will run in between the pranks White's team of oldsters pull on younger victims.

Season 2 of Off Their Rockers kicks off Tuesday, Jan. 8 with two back-to-back episodes beginning at 8/7c on NBC. White, who earned an Emmy nomination as Outstanding Host for a Reality or Reality-Competition Program for Season 1, turns 91 this January. A follow-up special to last year's highly-rated 90th birthday celebration is expected to air on NBC later this winter.
